Features: You may have had this experience countless times: You've almost picked all the correct numbers, but unfortunately, they are not in the same ticket, so you end up missing even the last prize. How can you avoid this frustrating situation? The surefire method, of course, is to use multiple bets. But this approach can be prohibitively expensive when dealing with a large number of numbers. For example, a multiple bet with 15 numbers costs 12,870 yuan; whereas using a rotating matrix to group numbers, you only need to spend 50 yuan to guarantee: If 15 numbers include 7 winning numbers, you can at least match 5 of them. In other words, with rotating matrices, you can operate more numbers with less money, expanding your chances of winning. The book provides almost all the matrices for up to 32 numbers, with detailed explanations for the commonly used ones. This book equips long-desired lottery players with a classic, effective grouping tool, and we believe it will make your lottery game even more exciting. Rotating matrices involve a combination design: covering design. Covering design, packing design, Steiner systems, and design are all combinatorial optimization problems in discrete mathematics. They address how to combine elements of a set to meet specific requirements.
